An amusement park ride has a moving platform attached to four swinging arms. The platform swings back and forth, higher and higher, until it goes over the top and around in a circular motion. In the diagram below, AD and BC represent two of the swinging arms, and DC is parallel to the ground
(line l). Explain why the moving platform AB is always parallel to the ground.

Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] y = ta

Irina-Kira [14]

Answer:

The inner function is $u = \pi x$ .

The outer function is $f(u) = \tan{u}$ .

$\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}$

Step-by-step explanation:

The inner function is the one we apply the outer function to.

$y = \tan{\pi x}$

We apply the outer function tangent to $\pi x$ .

So, the inner function is $u = \pi x$ .

The outer function is $f(u) = \tan{u}$ .

The derivative of a compositve function

$y = f(u)$ in which $u = g(x)$ is given by the following function.

$y^{\prime} = f^{\prime}(u)*g^{\prime}(x)$

$f(u) = \tan{u}$

$f^{\prime}(u) = \sec^{2}{u}$

$u = g(x) = \pi x$

$g^{\prime}(x) = \pi$

$y^{\prime} = f^{\prime}(u)*g^{\prime}(x)$

$\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}$

Find the amount in a bank account if you deposited $10,000 for 25 years at 6.25% interest compounded quarterly.

KengaRu [80]

Ok, so the formula for compound QUARTERLY is A=P(1+ʳ/n)ⁿᵗ.
P= The initial amount.
R= The Rate
T= The Time/Number of Years
N= Number of time interest is compounded per year. (In this case its 4 because it compounded QUARTERLY.)

So if you input the numbers, you will get A=10,000(1+0.0625/4)⁴⁽²⁵⁾
Now solve inside the parenthesis.
10,0 00(1.0625/4)⁴⁽²⁵⁾
Now you will need a calculator for the next part...
Do 1.0625/4 and times it by 10,000 .
You will get 0.0265265. You can't for get about the ⁴⁽²⁵⁾.
⁴⁽²⁵⁾=¹⁰⁰
2,656.25¹⁰⁰=

12. Find the distance between points P(-1, 2) and Q(-3, 4).

marusya05 [52]

Answer:

D=2.82

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$
